This package contains classes that allow easy access to EJBs.
The basis are AOP interceptors run before and after the EJB invocation.
In particular, the classes in this package allow transparent access
to stateless session beans (SLSBs) with local interfaces, avoiding
the need for application code using them to use EJB-specific APIs
and JNDI lookups, and work with business interfaces that could be
implemented without using EJB. This provides a valuable decoupling
of client (such as web components) and business objects (which may
or may not be EJBs). This gives us the choice of introducing EJB
into an application (or removing EJB from an application) without
affecting code using business objects.

<p>The motivation for the classes in this package are discussed in Chapter 11 of
<a href="http://www.amazon.com/exec/obidos/tg/detail/-/0764543857/">Expert One-On-One J2EE Design and Development</a>
by Rod Johnson (Wrox, 2002).

<p>However, the implementation and naming of classes in this package has changed.
It now uses FactoryBeans and AOP, rather than the custom bean definitions described in
<i>Expert One-on-One J2EE</i>.
